A wave has a wavelength of 125 meters is move a distance of 300 m in 15s. What is its frequency? please help

Answers

Answer 1

Answer:    Frequency of any wave = (speed) / (wavelength)

   = (300m / 15s) / (125m)

   = (300m) / (15s x 125m)

   =    (300) / (15 x 125)    (m/s-m)

   = 0.16 / sec = 0.16 Hz .

How long does it take for the speed of light and sound to travel around the world

Answers

-- Light travels straight, not around in a circle. But if it did, it would cover
a distance equal to the length of the equator in about 0.13 second.

-- At the speed of sound (in air at standard temperature and pressure),
it would take about 32.6 hours to cover the same distance.

If light intensity obeyed an inverse square law you would expect to find the intensity of light to decrease as the square of the distance increases? True or false

Answers

Inverse square law: $(I_(2) )/(I_(1))= (\frac{d{2} }{d_(1)})^2$
where
$I_(1)$ is the intensity at distance 1
$I_(2)$ is the intensity at distance 2
$d_(1)$ is distance 1
$d_(2)$ is distance 2

The inverse squared law state that intensity decreases in inverse proportion to the distance squared. So if light obeyed that rule, it will decreases its intensity as the square of the distance increases.

We can conclude that the correct answer is: true.
